    Riser Voids

    Our patented, steel-supported GRP (Glass Reinforced Polymer) Riser flooring system will help you take the hassle out of Risers and is designed for all construction stages and methods. Known as the d² Dura Riser System, it eliminates the risk of falling from height because the void is covered at the exact moment of installation, and services can be cut in situ without the need for costly removal of cover plates or adjustment to the support.

    Eliminates the risk of falling from height.

    Our bespoke first-class safety, riser solutions on new builds or refurbishments together with our highly experienced team offer a tried and tested one-stop-shop for Riser safety – including design, material supply & install. Using the d² Dura Riser system, services can be cut in situ without the need for costly removal of cover plates or adjustment to the supports.

    As well as offering the most comprehensive patented product range on the market, we pledge to do the necessary preparation to ensure that your riser project price avoids unwanted and unplanned extra costs for variations and hindrances thanks largely to our experienced and effective Site Supervisors, supported by our own PAYE staff for assured project delivery and continuity.

    Unlike competitor solutions, there is no need to cut service holes ahead of time or to crane heavy framework into position, and the system is infinitely adjustable to allow for millimetre by millimetre changes. All components of the Dura Riser solution are also suited to manual handling and can be easily adapted for use with unusual substrates.

    Safety or Warranty

    Defining the best approach for your Riser Voids

    Void Status

    ​​Q: Will the risers be installed before or after the void is formed?

    ​​Q: What are the load and deflection requirements?​

    A: Does your project require Point Load or UDL and to what deflection?

    Grating Type

    ​​​​​Q: How much activity will there be under the riser flooring?

    A: We offer supply-only or a full contract installation service using our PAYE staff for continuity.

    Assembly Methods
